To all whom t may concer/n."

Be it known that I, FERDINANDO ANTONI- a new and useful Coupling, of which the following is aspecication.

My invention relates to hose couplings,

and particularly to those suitable for coupling a hose yto a fire hydrant.`

An object of the invention is to provide a coupling which can Ibe connected or1disconnected very quickly.

Another object of the invention is to provide a coupling whichisconnected or dis connected with the hands only;`

The invention possesses other features of advantage, some of which, with theforegoing, will be set forth in the following description of the preferred form` of my invention which'is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do notlimit myself to the showing made by the said drawings and description, as I may adopt varia-tions of the preferred form within the scope of my invention as set forth in the claims.

Referring tothe drawings: Figure 1 is a half sectional view taken in a horizontal plane. f y

`Fig. 2 is a side elevation,` part ofthe structure being broken away.

Fig. 3 is a vfront elevation of the housing before theinsertion of the plug nozzle.` i

My invention comprises a housing 2 which is permanently attached by means of the, threaded annulartlange V3, to the ,nipple 4: of the frehydrant 6. The annularflange 3 extends into the"housing and terminates` therein in anannular seat 7. The flange 3 y thus forms an extension ofthehydrant nipple 4 and terminates in the seat 7 `against which the end of the plug nozzle 9 of the hose 10 abuts. Opposite the annular seat,"

the housing 2 is provided with a rectangular opening, the 'wall on that side,` forming only a narrow flange 11 adapted to` snugly surround the square body of the plug nozzle. The outside surface 11a of the flange 11is beveled to facilitate the entrance of the plug nozzle, and the end ofthe latter is` preferably provided with a gasket 12 formed "complementary to the seat 7, and adapted to permit a tight joint to be `formed,beti't'feen the `parts when the plug nozzle is pushed v y into the housing and upagainst the seat. FTTI, a citizen of Switzerland, anda resident of the city and county of San Fran- "cisco and State of California, have invented i Means are provided for closing the opening in the housing when the plug nozzle is withdrawn. On each side of the o-pening behind the` Harige 11, a `door 13 wide enough l to close half the opening, is pivoted on the pin 14, and a spring 16 tends to keep the doors'closed. In order to prevent wanton and unnecessary opening of the` doors, spring-pressed latches 17 are provided at top and bottom which lock the doors in the j closed position by engaging them innotches 17"therein.` These latches are arranged to "be released automatically when the plug nozzle ispushed against the doors. The

@end of each latchis finished flush with the surfaeell8 `of the flange 11, and a ridge 18` "is disposed upon thetop and bottom plates ment of the plugnozzlewith the flange 3,

inclined ridges 21 are disposed at the top and bottom of the housing.` Lugs 22 1"are disposed `o`n each side "to limitthe backward swinging of the doors 13. vAs the plug noz- `zl'elapproaches its seat, the doors 13 on the "sides and theridges 21 at top and bottom, accurately guide the end of the nozzle `and prevent lateral displacement thereof` on the Means are provided for retaining thenozzle 9 within the housing and uponthe seat ",7 so that a continuous and tight conduit is" formed, and this is accomplished by arranging latches`-`upon the plug nozzle` which automatically engage the housing when `the nozzle is thrust ir1`,`and whieh are manually released so that the nozzlemay be with drawn.` On both the top and bottom" of the plug nozzle, a pairoflatch levers 23 and 24 nozzle, "are withdrawn from their `seats orned' on the insideof thetlange 11. 'i The tively,` which project from the sides of the front edges 311 of the latch levers are beveled so that they oder no resistance to the entrance of thezphug.v nozzle .intov `.the housing,

and a spring 32 on each lever tends to kee the hooked ends 28 and 29 extended.y Thelr pivot upon which each latch lever is mounted is preferablyi the ysmooth shank of acaphooled .engagementsWiththe inside of. the f A flange V1l andseurelyretainthe nozzle upon i ple'terininating in.a.-seat, ala'terally closed i housing surroundingsaidg seat'. and. rigidly f fedltheretosand afplugfnozzle adePtGd-IO its.'` seat.
